L ie . I. Psychophysical invariants of achromatic colour vision. I. The multi‐dimensionality of achromatic colour experience. Scand. J. Psychol ., 1969, 10, 167–175.—The literature relevant to the question of multidimensionality of achromatic colour is briefly reviewed. An experiment confirms that the achromatic scale is bidimensional, and indicates that the dimension of brightness is a direct function of the luminance of the local area inspected, while the dimension of whiteness is a direct function of luminance relations of adjacent areas in the visual field.
